M9Pe
The M9Pe starts at $ 112 for the M.2 module with 256 GB without a cooler. The most expensive variant M9PeY with 1024 GB of storage space is offered with 462 US dollar. Instead of 2D-MLC-NAND as in the previous series, the new Plextor M9Pe memory contains new Toshiba 3D-TLC-NAND (BiCS3-Flash with 64 layers). Compared to the last generation, this represents a significant leap in performance. From 2500MB / s readable with the M8Pe series, the number jumps to 3200MB / s in the new models and 1400MB / s to write speeds up to 2100MB / s – as usual. However, these rates only apply up to the limit of the pseudo-SLC cache.

It had already become known in advance that the M9Pe will be based on the same controller as the predecessor – so here again the Marvell 88SS1093 is in use, which has three CPU cores and eight NAND channels and PCIe 3.0 x4 as an interface as well as NVMe 1.1 as a protocol uses. The power-saving mode L1.2 is also on board. As before, Plextor grants a 5-year guarantee, but the guaranteed minimum shelf life (TBW) is significantly reduced.
